Despite therapeutic progress, opportunistic oral fungal infectious diseases have increased in prevalence, especially in denture wearers. The combination of entrapment of yeast cells in irregularities in denture-base and denture-relining materials, poor oral hygiene and several systemic factors are the most probable cause for the onset of this infectious disease. Hence, colonization and growth o...

UNLABELLED Lymphangiomas are uncommon congenital hamartomas of the lymphatic system, usually diagnosed in infancy and early childhood. Commonly located at head and neck, they are rarely situated in the oral cavity. Preferred site of oral involvement is the tongue. In the absence of proper therapy, lymphangiomas of the tongue are extremely recurrent, leading to serious complications such as hemo...

In the assessment of the head and neck, differential diagnoses can be formulated by subdividing the anatomy into spaces along identifiable and logical boundaries. In the oral cavity, the root of the tongue is notably unlike adjacent regions due to structural and tissue-specific differences. The majority of lesions found in the root of the tongue are congenital and benign, representing ectopic t...

The infection of the retroperitoneal area (retroperitoneal abscess) is a relatively rare but serious infection, leading to considerable mortality. Most commonly, cases with retroperitoneal infection reported in the medical literature are as a complication of a local abdominal pathology. Retroperitoneal abscesses may be complicated with extension of infection into the peritoneal cavity, the pleu...

Schwannoma is a benign tumour that originates from the Schwann cells of the peripheral nerves. It presents as slow growing painless swelling in the oral cavity or head and neck region not often encountered in clinical practice. This sub mucosal lesion must be differentiated from other benign lesions that also appear in the same regions. Approximately 25 – 45% Schwannomas are seen head and neck ...

The ultimate objective of this research project is to develop creep damage constitutive equations for low Cr-Mo alloy and its weldment under low stress (0.2-0.4 yield stress, ��). This paper summarizes a critical analysis on the cavity nucleation and growth and the deformation mechanisms and creep damage evolution characteristics at low stress with temperature ranging from 450 °C to 650 °C, in ...

Abstract—This paper presents a low-loss coaxial cavity microwave bandpass filter with postmanufacturing tuning capabilities. A systematic filter development using a low-pass prototype as the starting point to produce a fourth-degree Chebyshev bandpass response is demonstrated. The coaxial cavity filter based on the transverse electromagnetic mode of the propagation has a center frequency of 2.5...

A pilonidal sinus is a blind-end tract lined with granulation tissue, which leads to a cystic cavity lined with epithelial tissue. As the name suggests, these hair containing abscesses are usually found in the sacro-coccygeal region. However, they may also occasionally occur in the axilla, groin, inter-digital web, umbilicus, nose, inter-mammary areas, supra-pubic area, clitoris, prepuce, penis...

A baby girl, weighing 2.5 kg, presented on day 1 of life with a bowel lying outside the abdominal cavity. She born at 38 weeks gestation by spontaneous vaginal delivery. Antenatal scans at 13 and 17 weeks detected gastroschisis. Her APGAR score was satisfactory. On examination, the bowel was eviscerated outside the abdominal cavity through the small defect at the lateral side of the base of umb...

Sapovirus (SaV) protease catalyzes cleavage of the peptide bonds at six sites of a viral polyprotein for the viral replication and maturation. However, the mechanisms by which the protease recognizes the distinct sequences of the six cleavage sites remain poorly understood. Here we examined this issue by computational and experimental approaches. A structural modeling and docking study disclose...
